Not 100% sure, but seems like a resource constraints issue. Have you tried running this again, getting the same result? Also, what kind of resources (CPU, RAM, etc.) are you allocating to this?

@Jon Zeolla - is on the right track. Your Kafka broker seems to have died and as a result, the Metron service start process cannot contact it to create the topics it needs. I'd recommend either using Metron's Full-Dev environment. If you're determined to get it running on the Sandbox, you'll need to do a resource sizing activity to make sure all the services can live in the amount of memory available to the container.

Thanks you ! I will try the Metron's Full-Dev.

@David Lyle , i only have a Cloud machine. Of course, when in run full-dev metron in my VM i get

"Stderr: VBoxManage: error: VT-x is not available (VERR_VMX_NO_VMX)" because nested virtualisation..

Do you have any idea to fix it?

I only took a quick look into this - it seems that as of Jun 3, 2014 AWS doesn't seem to support VT-x.
